VELUX Flat Roof Rigid Sun Tunnels are the ideal solution for bringing natural light into areas of the house where it is either not possible or not appropriate to install a flat roof window.
VELUX Flat Roof Sun Tunnels can transform a bathroom, cupboard or office space, flooding the room with natural light. When a VELUX roof window or flat roof dome is not possible, these innovative systems are the perfect choice.
- Recommended for tunnel lengths from 0.8 to 6 m between the roof and ceiling.
- The 1.7m long rigid tunnel should be used when greater lengths- in combination with ZTR extension sections- are necessary and to ensure adequate daylight levels are obtained. It is supplied with 2 x 45 degree bends.
- Can be extended to distances up to 6 meters.
- Rigid tunnel has a diameter of either 35cm or 25cm.
- Super reflective coating along the interior of the tunnel provides a 98% internal reflection rate.
- An easy-to-assemble diffuser comes complete with a frosted polycarbonate insulating frame.
- Roof module in PVC and an acrylic dome.
